Abstract: The ($\tau$,xnyp)-reactions on $^{197}$Au were measured. The $^{3}$He incident energy was between 15 MeV and 135 MeV. The experiments were carried out using the stacked-foils technique. Cross sections were determined from the activity of the residual nuclei. The ($\tau$, xn)-excitation functions were measured for 2$\le$x$\le$l0. Thus cross sections for E$_{\tau}$ $\leq$70 MeV as well as x$\leq$7 were measured for the first time. Further the ($\tau$,pxn)- and ($\tau$,2pxn)-excitation functions, which were not known so far, have now been measured. The analysis within the framework of the hybrid model for precompound-nuclear-reactions followed by an evaporation cascade, resulted in the best agreement between experimental data and theoretical model calculation using an initial exciton number n$_{o}$ =5 (ln+3p+lh). The region of validity of the hybrid model for complex projectiles is discussed.
